There was some quite heavy rain in the morning. However as we were leaving Santander it started to dry up. We headed south east for Zaragoza, about 4 hours drive away. On the way we stopped in a layby for our lunch.
We reached the aire we'd identified on the Search4Sites app, but didn't really like the look of it. It was just a lorry park next to a service station on the ring road.
However there is another free aire on the other side of the city near the university, which looked a better bet, so we headed there.
This was much better, though quite busy and we had to park in an overflow area. Like the Santander free aire, it had water and waste facilities provided.
We only had a short local walk, then ham croquettes with peas and sweetcorn.
